Create a perfectly seamless 16x16 pixel-art texture tile. STRICT RULES: - Exact resolution: 16x16 pixels. - Square image. - Flat 2D top-down view. - No perspective. - No 3D shading. - No border frame. - No gradient. - No blur. - No anti-aliasing. - Sharp nearest-neighbor pixels only. - Must tile perfectly horizontally and vertically. Subject: Grass and dirt mixed texture for a 2D game block. Color palette: - Dirt base: #8B5A2B - Dirt dark: #6E4523 - Grass green: #3FA34D - Grass light: #63C96D Structure: 1) Fill the entire tile with dirt base color (#8B5A2B). 2) Add small irregular dirt dark clusters (1–3 pixels). 3) Add scattered patches of grass green across the tile (not only at top). 4) Add a few grass light pixels inside the green patches. 5) Distribute everything evenly. 6) Avoid straight lines. 7) Avoid symmetry. 8) Do NOT treat edges differently from the center. 9) Texture must look natural and seamless when tiled. Expected result: Balanced mixed grass-dirt pixel-art texture, seamless tiling, clean 2D retro style. Ver más
